Teollisuuden Voima Oyj (TVO), owner and operator of the Olkiluoto nuclear power plant in Finland, has resumed Olkiluoto-3’s test production phase, following completion of maintenance and repair work at the new reactor’s turbine island, the company announced this week.

TVO had announced in June a delay to the unit’s commercial start of some three months—from September to December—after material that had detached from the steam guide plates was found in the turbine’s steam reheater in May, necessitating repair work and a halt to testing.

Teollisuuden Voima Oyj (TVO), owner and operator of Finland’s Olkiluoto nuclear power plant, has announced a further delay to the start of regular electricity generation at Unit 3. Commercial operation is now projected to begin this December, rather than the previously announced September. A report from Reuters puts the date at December 10.

According to TVO, material that had detached from the steam guide plates was found in the turbine’s steam reheater last month, requiring inspection and repair work.

Europe’s first EPR, Unit 3 at Finland’s Olkiluoto nuclear power plant, was connected to the nation’s grid on March 12, Teollisuuden Voima Oyj (TVO), the facility’s owner and operator, has announced.

Olkiluoto-3 is also the first new Finnish reactor in four decades, and one of only three new reactors in Europe in the past 15 years. (Romania’s Cernavoda-2 began supplying electricity to the grid in August 2007, and Belarus’s Belarusian-1 in November 2020.)

Framatome announced on February 22 that the Nuclear Regulatory Commission has approved a license amendment that would allow Framatome’s shipping containers to transport, in the United States, fresh nuclear fuel assemblies containing uranium enriched up to 8 percent uranium-235.

Light water reactor fuel with higher enrichments and burnup capabilities than currently used under low-enriched uranium regulation could improve electricity generation and fuel utilization, possibly improving plant economics and providing more flexible reactor performance through extended operating cycles and more efficient core configurations.

Westinghouse Electric Company and Southern Nuclear have agreed to a plan to install four Westinghouse lead test assemblies in Vogtle-2, a 1,169-MWe pressurized water reactor located in Waynesboro, Ga. Four lead test assemblies containing uranium enriched up to 6 percent U-235 will be loaded in Vogtle-2 in 2023, marking the first time that fuel rods with uranium enriched above 5 percent U-235 are put in use in a U.S. commercial power reactor.

Predictions: What lies ahead for nuclear in 2022

January 21, 2022, 3:26PMNuclear News

As we begin a new year, it is natural not only to look back (see page 24 for top news stories of 2021) but also to look forward. Nuclear News reached out to leaders in the nuclear community to get their predictions on what 2022 has in store, whether broadly or for their specific areas within the community. Although the responses below are wide-ranging and varied, one thing is made clear by all of the respondents: 2022 will see growth and opportunity. The future for nuclear is bright.

A longstanding issue in boiling water reactors—shadow corrosion on zirconium alloy fuel rods and fuel channels—has been reproduced in the Michigan Ion Beam Laboratory as part of an effort to understand and prevent the phenomenon. Research led by Peng Wang, a University of Michigan assistant research scientist in nuclear engineering and radiological sciences, was published in the January 2022 issue of the Journal of Nuclear Materials and described in a recent university news article.

GEH’s BWRX-300 SMR technology chosen for Darlington clean energy project

GE Hitachi Nuclear Energy has been selected by Ontario Power Generation as technology partner for the Darlington site's new nuclear plant project. GEH will work with OPG to deploy a BWRX-300 small modular reactor as early as 2028 at the Darlington site in Canada.

■ NuScale Power and Kazakhstan Nuclear Power Plants LLP have signed a memorandum of understanding to explore the deployment of NuScale VOYGR power plants in Kazakhstan. KNPP specializes in the development of nuclear power plant construction in Kazakhstan. The agreement calls for a sharing of nuclear and technical expertise between NuScale and KNPP. Under the MOU, NuScale will support KNPP’s evaluation of NuScale’s SMR technology, including nuclear power plant engineering, construction, commissioning, operation and maintenance, and project-specific studies and design work.

PKN ORLEN and Synthos Green Energy have signed an agreement to set up a joint venture, ORLEN Synthos Green Energy, with a goal to prepare and commercialize small nuclear reactor technology, particularly GE Hitachi Nuclear Energy’s BWRX-300 reactors, in Poland. Related, BWXT Canada Ltd. signed a letter of intent with Synthos and GEH for the manufacture of key SMR components for Poland.

Nuclear fuel considerations in the development of advanced reactors

The world faces an urgent need to decarbonize and expand clean energy systems. Earlier this year, the United States announced goals to achieve a 100 percent clean electricity grid by 2035 and net-zero emissions across the entire economy by 2050. Today, nuclear energy plants provide more than 50 percent of the United States’ carbon-free energy. Existing plants, along with the advanced technologies currently being developed and demonstrated, are crucial to the United States’ and the world’s clean energy future.

Technologies such as advanced non-light water reactors, which have higher operating temperatures than today’s light water reactors, will be vital to meeting economy-wide decarbonization goals. For example, process heat applications and chemical and synthetic fuel production require higher temperatures and currently rely on fossil fuels. Advanced reactors are the only carbon-free technologies that can provide the high temperatures these processes need.

NuScale Power has signed a memorandum of understanding with Prodigy Clean Energy and Kinectrics to explore and inform the development of a regulatory framework to address the licensing and deployment of a marine power station (MPS). The MPS would integrate one to 12 NuScale power modules into a marine-based nuclear power plant system. The MPS would be shipyard-fabricated and marine-transported to its deployment location, where it would be moored in place in sheltered and protected waters at the shoreline. Prodigy is Canada’s first commercial marine nuclear power developer, specializing in integrating existing power reactors into stationary-deployed marine power plant structures. Kinectrics provides life-cycle management services to the electricity industry.

The nuclear industry’s first 100 percent accident tolerant fuel assembly is in operation at Exelon Generation’s Calvert Cliffs plant, the Department of Energy announced yesterday. The advanced fuel will operate in the reactor for the next four to six years and will be routinely inspected to monitor its performance, the DOE said.

Located in Lusby, Md., Calvert Cliffs houses two pressurized water reactors. Unit 1 is rated at 907 Mwe, and Unit 2 at 881 Mwe.

The first of eight 160-ton steam generators for Unit 6 at Canada’s Bruce nuclear power plant was installed last week as part of the facility’s major component replacement project. “Congrats to the MCR team and our partners, including @AeconGroup, @Framatome_CA, @UEandC, @mammoetglobal, @BWXT, and others who contributed to this historic moment,” Bruce Power tweeted on September 30.

The component was fabricated at BWXT Canada’s Cambridge, Ontario, location and was shipped to the Bruce site in late 2020, as shown in this video.

The vendor responsible for generator removal is the Steam Generator Replacement Team (SGRT), a 50-50 joint venture between Aecon and the Steam Generating Team, itself a partnership between Framatome and United Engineers & Constructors. In July, Framatome announced that SGRT had been awarded an approximately C$350 million (about $278 million) contract by Bruce Power to replace the steam generators at Units 3 and 4.
